Computers
and Structures, Inc. is proud to release CSiBridge, a new comprehensive
state-of-the-art software product for the structural & seismic
analysis, design and rating of simple and complex bridges. All
operations are integrated across a single user interface that provides
an easy-to-use and intuitive workflow environment. Bridge models are
created parametrically resulting in enhanced productivity, saving
engineering time while redefining the standards of accuracy and
versatility.

• Abutments may be modeled as bents
• Bearing properties and location may be user defined
• Kinematic effects due to abutment and bearing geometries are included
• Bridges may be analyzed as full 3D-shell or spine models

A new option has been added for the modeling
of I-girders in composite steel-girder superstructure sections. In
addition to the existing options to model the I-girders as frame
objects or as area objects (for both web and flanges), the girders can
now be modeled using area objects for the webs and frame objects for
the flanges.

A new bridge seismic design check has been
added to the Chinese version that follows the Chinese code JTG/T
B02-01-2008, "Guidelines for Seismic Design of Highway Bridges".

Bridge design for prestressed concrete box
girder superstructures using Chinese code “JTG-D62-2004” in the Chinese
version has been updated as follows: (1) The effect of existing
longitudinal rebar is now accounted for in flexural design. (2) A new
design check has been added for tendon stress.

The Chinese 2002 building design codes are available for concrete and steel frame design in the Chinese version.

Concrete frame design has been enhanced to
improve the smoothing of P-M-M interaction surfaces in those rare cases
where they become non-convex due to kinks in the P-M curves.
